“…[13,33,34] The value of isoelectrical point of the oxide and the hydroxylated aluminium oxide on the surface of aluminium sheet is about 9-9.2. [33,34] So, the aluminium oxide and the hydroxylated aluminium oxide on aluminium surface will be positively charged when dipping the aluminium sheets into the γ -APS aqueous solution in ethanol. According to the mechanism of acid and base interactions, the negatively charged silanol groups will interact with the positively charged aluminium oxide and hydroxylated aluminium oxide.…”

“…Chemical (adhesion) bonds can be detected with different methods [6,7]. According to [8], the adhesive interaction in the presence of water is determined by the isoelectric point of a hydroxylated oxidized metal surface ( pH IEPS ) and the acid dissociation constant ( p K α ) of a polymer's polar group.…”

Effect of water on the electrical double layer structure at a metal/polymer interface is studied with the use of scanning vibrating capacitor and electrochemical impedance spectroscopy. In the initial stage, the Volta potential of the contact changes well reversibly and rapidly, being proportional to the water vapor pressure, following its diffusion in the polymer ( ∆ V = A + B log (time) 1/2 ). Water dipoles at the metal/polymer interface orientate counter the field and compensate it. Drying of the contact restores the initial potential drop. In the first stage of exposure, water somewhat enhances the interfacial interaction, which manifests itself in increasing the potential drop, as well as the charge transfer resistance, and in decreasing the capacitance of the electrical double layer. As time passes, the interface hydrolyzes, its capacitance grows and the time of subsequently restoring the electrical double layer by drying increases. Kinetic dependences of the potential and capacitance, exhibit two segments, we ascribe to easily removable and strongly bonded water molecules solvating the interface, respectively. It is shown that metal-polymer interfacial bonds passivate the metal; however, the passivation can be broken down because of the hydrolysis and the interfacial moisture film formation.

“…For the coating containing IBA-Fe 3 O 4 , the wet adherence improvement can be also attributed to the IBA release in the presence of water, which reacted with iron oxides at the steel surface. 36 From the cross-cut test, it was not possible to discriminate between the adherences of the three systems at the initial state (as-prepared samples). Thus, the three-point bending test was performed to better characterize the interfacial phenomena (the failure initiation is well defined in this test) at the initial state (i.e., before aging).…”
